SPECIFICATION forming part of Letters Patent No. 594,803, dated November30, 1897. Application filed February 17, 1897. $erial No, 623,823. (Nomodel.)

To all whom it may concern;

Be itknown that I, OSCAR KUSTEL, acitizen of the United States, residingin the city and county of San Francisco, State of California, haveinvented an Improvement in Mariners Compasses; and I hereby declare thefollowing to be a-full, clear, and exact description of the same.

My invention relates to improvements-in a mariners compass.

It consists in a novel construction of the compass-card and the meansfor supporting the magnetic needles employed therewith and in details ofconstruction, which will be more fully explained by reference to theaccompanying drawings, in which Figure 1 is a plan view of my improvedcard. Fig. 2 is a vertical section showing the card and the magneticneedles.

The object of my invention is to provide a compass-card and support forthe magnetic needles employed therewith of the lightest possibleconstruction consistent with permanency.

In the construction of my card I employ a woven texture of any suitabledescription, preferably of silk. This card A has its periphery fixed toa light aluminium rim B, and at the center is connected with the boss C,which is balanced and turns upon the pivotpin 1) below. The points ofcompass, letters, &'c., are marked around the periphery of the wovenfabric, which extends in a continuous body from the rim to the center.This construction provides an exceedingly light card, and the materialis of such a nature that it does not warp, expand, or contract unduly orget out of shape in any manner by the action of cold or heat.

The magnetic needles E, which give direction to the card are fixed in aband F, of woven material, which is also preferably of silk and whichmay have its ends attached to the peripheral rim B of the card, the bandextending across beneath the compass-card and supporting the needles, asshown.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a mariners compass, a compass-card formed of woven material havingthe points marked upon it, a supporting peripheral rim,-

and a band of woven material extending across from side to side of therim and adapted to support the magnetic needles.

-' 2. In a mariners compass, a compass-card composed of a continuouscircular sheet of woven material with a pivotal center and a peripheralsupporting-rim, the surface of the card having the points of compassmarked thereon and a support for magnetic needles consisting of a bandto which the needles are fixed extendingv from side to side of the rimand crossing below the center of the compasscard.

"In witness whereof I have hereunto set my hand.

OSCAR KUSTEL.
